Occasional Starting problems

[adamgroves]

This has happened twice now in three days.

When i go to start the car, it turns over fine but doesnt fire, i have to keep nudging the throttle to get it goin, and even then its a struggle, when i finally get it goin, it runs really rough for about 3 seconds then the revs jump up to around 2000 rpm and then it settles back down and the car is then fine.

The car shouldn't be particularily cold when its happened on these occasions as i'd been out in it about an hour or so before both times?


Can anybody help as its under warrenty and would like some amo to go to the dealer with.

Sometimes the fuel pumps get old and they leak the pressure from your fuel system, so when you come to start it fuel has be pumped back in to pressurize the system again. This had been quite commom try some searches on audi world including tt's (same motors as s3 a3)
The symtoms of this would be....... The car would be a little hard to start after you leave it for an hour or so ... hot or cold.
Hope this helps

Mine does this when fuel is low. I have to make sure it's got half a tank or more and it's fine. Fuel pump is probably struggling, so needs the additional weight of fuel. Keep meaning to change the fuel filter as well as there was a post on here about the fact they don't get changed on services, so mines probably the original.

Oldish car??

COOLANT TEMP SENSOR!!

Change it now!! I had the exact same symptoms just when the cold started.
Cheap part too. Make sure you get the green top one.
